The Heckler & Koch HK45 Compact Tactical (CT) is a rugged, .45 ACP semi-automatic pistol favored by special operations. It features an extended threaded barrel for suppressors, high-profile sights, and a 10-round capacity. A closest a civilian can get to that military pistol. Cold hammer-forged barrel equipped with an O-ring for improved lockup and accuracy when a suppressor is attached. Includes an ambidextrous slide release and magazine release located on the trigger guard. Polygonal Rifling Results in longer barrel life and an increase in muzzle velocity. An “O-ring” barrel means better slide-to-barrel lockup and enhanced accuracy. And the threaded barrel on the HK45 CT is made using the famous HK cold-hammer forging process for superior performance.
